Fast Charging s6 on screen but incredibly slow.

[AC Question]

When I try to charge my S6 I get the fast charge message and relatively low charging time, however it always takes far longer despite that message. The charging port no longer heats up when fast charging either. I have tried pushing all detachable parts as I far as they will go, and selected fast charging in the settings. I have also tried cleaning out the ports with a pin.
Can anyone help? I am beginning to be concerned this is an issue with the phone's charging port.
Any help appreciated.

How slow is slow anyway? I mean how long is it taking you to full charge?

Wipe system cache first off.

Try a different cable.
